Description

Technical Field

[0001] The utility model belongs to the technical field of slush-molded skin structures and relates to a vinyl chloride skin, in particular to a luminous polyvinyl chloride skin. Background Art

[0002] Polyvinyl chloride (PVC) is widely used in automobiles, such as automobile sealing strips, the surface of automobile dashboards, and automobile sunroof drain pipes. At present, the surface of automobile dashboards is usually made into powder first, and then formed into the surface through the slush molding process; after the PVC surface is formed, the surface color and pattern are relatively monotonous, which is difficult to meet people's needs.

[0003] The Chinese invention patent with application number 202110988185.1 discloses a soft-touch luminous decorative material and its preparation method and application, which belongs to the technical field of automotive interior materials. The soft-touch luminous decorative material includes a light-transmitting epidermis layer 1, a pattern layer, a light-transmitting epidermis layer 2, a light-transmitting soft touch layer, a light-transmitting skeleton layer and a backlight source from top to bottom. The pattern layer in this application is obtained by high-definition digital printing using quick-drying ink, and the color and use effect of the pattern layer change with the change of the backlight source; this obviously leads to the complex structure and process of the soft-touch luminous decorative material and high cost.

[0022] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0023] Example 1

[0024] This embodiment provides a luminous polyvinyl chloride skin, which includes a skin layer 20. The skin layer 20 mainly includes a main body unit 1 and a light-emitting unit 2.

[0025] Among them, at least one groove 11 is provided on the main unit 1 (usually on its surface), and the actual number of grooves 11 can be conventionally selected according to actual needs (the existing conventional method of providing the grooves can be adopted, such as mold forming or laser cutting, etc.). The thickness of the groove 11 can be equal to or less than the thickness of the main unit 1; but it is preferably less than the thickness of the main unit 1. At this time, the groove 11 does not penetrate the main unit 1, and the thickness of the light-emitting unit 2 filled here can be reduced to save costs. The light-emitting unit 2 is correspondingly embedded in the groove 11, so that the light-emitting unit 2 corresponds to the groove 11 of the main unit 1 one by one; the light-emitting unit 2 is also combined with the main unit 1, and the combination method therebetween is glue bonding or hot pressing bonding, preferably hot pressing bonding, which can not only reduce the use of glue, but also make the polyvinyl chloride surface more environmentally friendly.

[0026] In this embodiment, the main unit 1 is made of conventional PVC plastic material, and the light-emitting unit 2 is preferably a luminous material, that is, a material that absorbs light during the day and emits light at night. In addition, the groove 11 can be processed into any shape according to actual needs, such as a corporate logo, text (including foreign text) or pattern, and the light-emitting unit 2 can also be processed into a corresponding shape. For example: Figure 1 As shown, the shape of the groove 11 corresponds to the Chinese character "I love singing", and the light-emitting unit 2 is formed by pressing the light-emitting material into a sheet by a tablet press, and then cutting it into a shape corresponding to the Chinese character "I love singing" by a mold.

[0027] In this embodiment, the thickness of the epidermis 20 (equivalent to the thickness of the main unit 1) is 0.8~2mm, and the thickness of the light-emitting unit 2 is 0.7~1.9mm (at this time, the thickness of the light-emitting unit 2 is equal to or less than the thickness of the main unit 1, preferably less than the thickness of the main unit 1).

[0028] Example 2

[0029] This embodiment provides a luminous polyvinyl chloride skin, which is basically the same as that in the first embodiment, that is, it mainly includes a main unit 1' and a light-emitting unit 2'. The main unit 1' is provided with at least one groove 11', and the light-emitting unit 2' is correspondingly embedded in the groove 11'. The difference is: Figure 2 As shown, the shape of the groove 11 ′ corresponds to the English word “Westlake” (our company logo), and the light-emitting unit 2 ′ is formed by pressing the light-emitting material into thin sheets by a tablet press, and then cutting the thin sheets into the shape corresponding to the English word “Westlake” by a mold.

[0030] Example 3

[0031] This embodiment provides a luminous polyvinyl chloride skin, which is basically the same as that in the embodiment 1, that is, it mainly includes a main unit 1'' and a light-emitting unit 2''. The main unit 1'' is provided with at least one groove 11'', and the light-emitting unit 2'' is correspondingly embedded in the groove 11''. The difference is: Figure 3 As shown, the shape of the groove 11 ″ is a star pattern, and the light-emitting unit 2 ″ is formed by pressing the light-emitting material into a sheet by a tablet press, and then cutting it into a corresponding star pattern by a mold.

[0032] Example 4

[0033] This embodiment provides a luminous polyvinyl chloride skin, which includes the skin layer 20 in embodiment 1 (of course, the skin layer in embodiment 2 or embodiment 3 can also be used), and also includes a UV coating 10, a foaming layer 30 and an adhesive layer 40, such as Figure 4 shown.

[0034] Among them, the UV coating 10 is formed on the surface of the epidermis layer 20 by a conventional coating process, and it covers the light-emitting unit 2 and blocks the light-emitting unit 2 (the color of the UV coating 10 does not completely block the light emission of the light-emitting unit 2, but it is preferably transparent); that is, the UV coating 10 is usually formed on the outer surface of the epidermis layer 20 (that is, the surface of the luminous polyvinyl chloride epidermis facing the consumer when in use). At this time, the introduction of the UV coating 10 overcomes the defects of the epidermis layer 20 being easy to accumulate dust, difficult to clean, and not scratch-resistant, so that the luminous polyvinyl chloride epidermis is easy to clean and scratch-resistant during use. The thickness of the UV coating 10 is preferably 10~50μm.

[0035] The foaming layer 30 is formed on the other surface of the skin layer 20, and its material is a conventional polyurethane foam material (PU), and its thickness is preferably 1-5 mm. The bonding layer 40 is formed on the outer surface of the foaming layer 30 (i.e., the surface away from the skin layer 20), and is used to bond the foaming layer 30 and the substrate to be covered (such as automobile dashboards, furniture, etc.), and can be selected from conventional existing glue or film, and its thickness is preferably 20-50 μm.

[0036] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
